Osgood-Schlatter's disease is a well known entity affecting the adolescent knee. Radiologic examination of the knee has been an integral part of the diagnosis of this condition for decades. However, the soft tissue changes have not been appreciated sufficiently. Emphasis is placed on the use of optimum radiographic technique and xeroradiography in the examination of the soft tissues of the knee.

A case of exsanguinating rectal and retroperitoneal hemorrhage resulting from a ruptured inferior gluteal artery aneurysm is presented. Transcatheter embolization of Gelfoam and a Gianturco coil device resulted in the control of bleeding and proved to be a life-saving measure in a patient who was a poor surgical candidate.
